BIOLUMINESCENCE: emission of light by living organisms (attraction, defense, warning, communication, mimicry, illumination)Bioluminescence was an intervention in Granary Square for Unannounced Acts of Publicness organised by AIR. Seven cyclists traversed / circled the public space in oscillating between tight formality (suggesting the peloton or flying patterns) to something loose and wayward and apparently coincidental. The cyclists wore unifying but not identical hi-vis yellow clothing and appeared and disappeared from each entrance to the square.The performance was intended to celebrate cyclists (their slightly anarchic presence as they navigate the city, critical mass cycle ides) and as a response to highly designed and orchestrated conditions of the square with its tides of footfall and synchronised fountains.
